At TechCrunch Shanghai, one of China’s largest hackathons, I worked with a team of developers to solve a multinational car brand’s biggest digital problem: boosting user engagement.

Use PSA Peugeot Citroen’s SDK and Open Data to build an iWatch application that allows users to engage with both their car and PSA after the point of purchase.

Design Process

Understand the Problem and Client – Researched the auto industry and PSA’s individual problems and opportunities

Skills Inventory – Took “inventory” of what skills, resources, and experiences our team of five possessed in order to determine the best product for us to create.

Brainstorm – Looked at possible problems we could successfully tackle given our time limit and skills

Designed a WatchOS app that helps PSA, the sponsor company, engage their user base.

Wireframing – Used ideas from brainstorm to develop wireframes of a watch OS application

Designed User Interface – Created user interface using Sketch while the developers created the prototype

Collected Feedback From Other Hackers – Conducted basic user testing to see problems and opportunities for improvement

Iterated – Iterated designs to reflect user feedback

The app also gives PSA a direct channel of communication to their customers - an extremely valuable tool for the car brand.

Constructed a Business Model – With product in mind, we created a lean business model including revenue opportunities and value proposition


Leveraged familiar user interactions and two option decision making to help drive PSA's business model.

Presented – I presented our product to the judges, highlighting its usability and unique value proposition to over 200 attendees

Presented our product to a panel of judges and an audience of over 200




Developed wireframes and a final user interface for a watch OS application that allows users to monitor the “health” of their car.
